Folded Perovskia

#637fd0
Notes

Folded Perovskia (#637FD0) is a true blue with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (225°, 54%, 60%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Folded
adjective

Old English fealdan, to fold — past-participle of fold. As a color modifier, folded implies a clear-and-creased-and-arranged quality where the hue carries the visual register of carefully-folded-and-neatly-arranged textile surface. Sits at the crisp-and-finished end of the grid, parallel to pressed and trim in usage.

Perovskia
noun

The genus PerovskiaRussian sage, the Central Asian woody perennial whose silver-leaved deep blue-violet flower spikes brave drought and cold. The color refers to a fresh Perovskia atriplicifolia in late summer: a saturated, slightly cool deep blue-violet with the matte finish of small clustered mint-family flowers along upright stems.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
